The Xindian Creek (or Xindian River) (Chinese: 新店溪; pinyin: Xīndiàn Xī; Wade–Giles: Hsin1-tien4 Hsi1) is a creek in northern Taiwan. It flows through New Taipei and the capital Taipei for 82 km.
The Xindian Creek is one of the three major tributaries into the Tamsui River. Its main tributary is the Beishi River which originates in Shuangxi District, New Taipei City at an elevation of 700 meters. The Feitsui Dam spans the Beishi southeast of Taipei. It flows west past Xindian before merging with the Nanshi River; it is at this point that it becomes "Xindian Creek". It then turns north and merges with the Chingmei River, before finally merging with the Dahan Creek and feeding into the Tamsui River.
The creek is one of the main sources for drinking water in Taipei City. According to the Taipei City Running Water Center, over 4 million Taipei residents obtain 97% of their drinking water from the river. The first bridge over the creek was constructed in 1937 and at 200 meters long connected the areas of Zhonghe and Xindian. Today, there are 22 bridges that span the creek.
The Xindian Creek is heavily polluted by both raw sewage and industrial pollution from illegal industry. The natural watercourse restoration is on the agenda of the Taipei City Government, Taiwan Central Government and several citizen organizations.
